Joe Activation with a WiFi-Controlled Electrical Outlet

1 year ago

[Mike] is the only one in his house who drinks coffee, and uses a simple single-serving brewer with no auto-on feature. And since no one really wants to have to stand around making coffee in the morning, [Mike]’s solution was to IoT-ize his electrical socket.

The project consists of a relay board controlled by an ESP8266-packing Adafruit Huzzah. It’s all powered by a 9V power supply with a regulator supplying the relay coil and Huzzah with 5V. [Mike]’s using CloudMQTT to communicate with the outlet.

We often see these automation projects hit a wall when it comes to adding a user-side dashboard. [Mike] is using a free Android app called MQTT Dash which allows for a number of different UI components and even had coffee maker icons already built in. It’s certainly worth a look for your own projects. [Mike] uses it to turn on the outlet for 10 minutes, and by the time he grabs half-and-half the outlet is already off again.
